JAVIK Rear Live Axle Bearing Kit 1in 3-Hole for Go-Karts & Mini Bikes — Sealed Bearings, Universal Fit

JAVIK's 1" rear live axle bearing kit is a complete 3-hole mounting solution to replace or upgrade the rear axle bearings on go-karts, mini bikes, trikes and small ATVs.

This ready-to-install kit is engineered for universal 1-inch solid axles and includes all the hangers, bearings and fasteners needed to repair worn mounts or convert older frames for smoother rear-wheel operation. It’s designed for hobbyists and small-shop mechanics who want a durable replacement that reduces axle play and noise without complex machining.

How will this kit improve my kart’s rear axle performance?

Replacing worn hangers and bearings restores proper axle alignment and minimizes lateral play that causes wheel wobble and noise. These parts fit standard 1" axles and clamp securely to the frame so the wheel rotates with less resistance and vibration.

• Includes two sealed axle bearings for reduced maintenance and longer life
• Bearing hangers position and support the axle to eliminate side-to-side movement
• Flangette plates and locknut hardware ensure a tight, lasting installation

What exactly comes in the package and is any special tooling required?

The kit comes with every fastener you need for a basic swap: bearing hangers, axle bearings, flangettes and a bolt/locknut set. No specialized tools are necessary for many frame types — a basic wrench, socket set and hammer or press for seating bearings are typically sufficient.

• 2x Bearing hangers to mount to a 3-hole pattern on the frame
• 2x 1" axle bearings (sealed) for direct axle support
• 4x Bearing flangettes to secure wheel mounting surfaces
• 1x Bolt and locknut kit for clamping the assembly

Will this fit my vehicle model and how do I confirm fitment?

The kit is designed for universal 1" live axles used across many small karts, mini bikes, trikes and off-road ATVs. To confirm compatibility, measure your axle diameter (should be 1 inch) and verify your frame has — or can be drilled for — a 3-hole hanger pattern to accept the bearing hangers.

• Measure axle diameter: 1" required for direct fit
• Check or mark a 3-hole mounting pattern on your rear frame crossmember
• Contact JAVIK support for fit questions or measurements if unsure

How long will these parts last and is there support if something goes wrong?

Durability depends on riding conditions and maintenance, but the sealed bearings and steel hangers are made to withstand typical hobby and light off-road use. JAVIK includes customer support and a limited one-year warranty to address defects or early failures.

• Sealed bearings reduce dirt and moisture intrusion for longer service life
• Steel hangers resist bending under normal loads when properly installed
• JAVIK offers 24-hour customer service plus a one-year warranty

Who is this for: This bearing kit suits DIY mechanics, kart hobbyists, small-race teams and anyone rebuilding or upgrading the rear axle assembly on 1" live-axle go-karts, mini bikes, trikes or compact ATVs. It’s a practical, cost-effective option when you need to remove axle play, eliminate noise, or convert an older frame to accept sealed bearings without custom fabrication.
